Explanation:

Statement 1: The sources of the Benguela Current include Indian and South Atlantic subtropical thermocline water; saline, low-oxygen tropical Atlantic water; and cooler, fresher subantarctic water.
The Benguela Current draws icy-cold waters from the Southern Ocean and carries them northward along the coast of Africa. Because of these cold waters, rain clouds do not develop over the southwest coast of Africa, contributing to the parched climate of the KALAHARI and Namib deserts.

Statemen 2: When the warm and the cold currents meet, dense fog is created. This is because air above the warm currents is warm which contains water vapour. When this warm current meet the cold current, the air above the cold current, causes the water vapour of the warm current to condense into tiny particles which form fog.
